WebJan 18, 2024 · ∙ share In this paper, we present an efficiently encodable and decodable code construction that is capable of correction a burst of deletions of length at most k. The redundancy of this code is log n + k (k+1)/2loglog n+c_k for some constant c_k that only depends on k and thus is scaling-optimal. The code can be split into two main components.

WebJul 20, 2024 · Optimal Codes Correcting Localized Deletions. Abstract: We consider the problem of constructing codes that can correct deletions that are localized within a certain part of the codeword that is unknown a priori. Namely, the model that we study is when at … Webconstructed two-deletion correcting codes that require 8log n oplog n q and 7log n oplog n q bits of redun-dancy, respectively. In [6], a t-deletion correcting code with O ptlog n q bits of redundancy was proposed. A t-deletion correcting code with 8 tlog n oplog n q bits of redundancy was given in [17].

WebError-correcting codes. We will study the design of error-correcting codes over sets that are suitable for data storage in DNA. Errors within this model are losses of sequences and point errors inside the sequences, such as insertions, deletions, and substitutions.
WebIn addition, he showed that the codes constructed by Varshamov and Tenengolts (VT codes) [7] are capable of correcting a single deletion and have asymptotically optimal redundancy1. Several previous works studied the classical problem of constructing binary codes that correct k > 1 deletions that are arbitrarily located in a string [8]–[16].
